GE IC695CPU315-CD

Description

The GE IC695CPU315-CD is a high-performance central processing unit for GE Fanuc’s RX3i PACSystems platform. This advanced controller delivers exceptional processing power for complex automation applications requiring high-speed logic execution, extensive memory capacity, and seamless integration with both legacy GE and third-party systems. The GE IC695CPU315-CD represents the mainstream controller choice for medium-to-large scale industrial applications, bridging the gap between traditional PLC functionality and modern PAC capabilities.

Technical Specifications
The GE IC695CPU315-CD features a 1.1 GHz Intel Celeron M processor with 10 GB user memory for application logic and 256 MB battery-backed SRAM for fast-executing variables and retentive data. The module supports up to 512 program blocks with individual block sizes up to 4 MB. Built-in communication includes dual 10/100/1000 Mbps Ethernet ports supporting SRTP, Modbus TCP, and OPC UA server functionality, plus a dedicated RS232 serial port for local programming access. The GE IC695CPU315-CD includes a removable SD memory card slot for program storage, data logging, and firmware updates. Operating temperature range is 0°C to 60°C with 5% to 95% non-condensing humidity tolerance. Power consumption is 13.5 W from the RX3i backplane.

Key Features and Advantages

• Multi-Processor Architecture: The GE IC695CPU315-CD executes logic, motion, and process control simultaneously using dedicated co-processors, preventing single-task bottlenecks.

• Large Program Capacity: 10 MB user memory supports extensive application code including multiple axis motion profiles, PID loops with adaptive tuning, and comprehensive HMI/SCADA interfaces.

• CRA Clipping Compatible: Fully supports GE’s Centralized Redundancy Architecture with bumpless transfer between redundant processor pairs for high-availability applications.

• Built-in Web Server: Embedded HMI interface accessible via standard browser for remote monitoring and diagnostics without additional software licensing.

• Universal Backward Compatibility: Executes logic originally developed for Series 90-30, Series 90-70, and earlier RX3i processors without requiring complete program rewrites.

Application Areas
The GE IC695CPU315-CD is extensively deployed in automotive assembly transfer lines, where its deterministic Ethernet capabilities synchronize hundreds of servo axes across multiple machine zones. A major North American tire manufacturer recently selected the GE IC695CPU315-CD as their standard controller for rubber mixing and tire curing lines, replacing multiple proprietary controllers with a single unified platform. The module is also widely specified in municipal water/wastewater treatment facilities requiring complex regulatory reporting, batch sequencing, and high-speed lift station control. Renewable energy applications include utility-scale solar tracking systems and wind farm power management controllers.

Competitive Comparison
Versus the Rockwell ControlLogix 1756-L83E and Siemens S7-1515-2 PN, the GE IC695CPU315-CD offers superior program memory capacity at equivalent price points and more flexible built-in Ethernet options with three Gigabit ports versus one or two Fast Ethernet ports on competitors. The GE IC695CPU315-CD uniquely supports OPC UA server functionality embedded directly in the controller without requiring additional hardware or software licenses, providing significant cost savings for enterprise-level data integration. Its native backward compatibility with legacy GE platforms reduces migration costs compared to competitor systems requiring complete application conversion. The universal auto-tuned PID capability also exceeds the fixed-coefficient algorithms found in many competitive PACs.

Selection Guidelines and Precautions

• Verify that your GE IC695CPU315-CD is ordered with the correct operating system version; -CD suffix indicates standard controller, while -CD/HR variants include high-reliability screening for extended temperature applications.

• Confirm that existing Series 90-30 or 90-70 programs do not exceed 10 MB after conversion; extremely large legacy applications may require code optimization.

• The GE IC695CPU315-CD requires Proficy Machine Edition version 8.0 or higher for configuration; earlier versions cannot access all processor features.

• Ensure that backplane power supply capacity exceeds total system load; the GE IC695CPU315-CD draws 13.5 W, which combined with high-power I/O modules may require the 40 W power supply option.

• Order the GE IC695CPU315-CD with the IC695ACC304 battery kit for extended data retention during prolonged power outages.

• When using redundant Ethernet networks, configure each port of the GE IC695CPU315-CD on separate subnets to prevent routing conflicts.

• The GE IC695CPU315-CD supports up to 512 axes of motion over Ethernet; confirm network topology and switch capacity when implementing large motion systems.
